    Abstract: A mobile device performs thermal management during concurrent battery charging and workload execution based on a thermal headroom. The thermal headroom is an amount of power, in a form of heat, that heat dissipation hardware in the mobile device is estimated to dissipate when the mobile device operates at a target temperature. After the thermal headroom is determined, the mobile device determines a first power allocation to system loading, which is caused by one or more applications running on the mobile device. The first power allocation is subtracted from the thermal headroom to obtain a second power allocation to a charger, which charges a battery module of the mobile device while the one or more application are running. The mobile device then sets an input power limit of the charger based on the second power allocation.

    Abstract: Methods and apparatus are provided for adjusting the power limit based on multiple factors including the current temperature, the previous temperature, and the target temperature. In one novel aspect, the device obtains the total power limit based on the base power and the delta power. The base power is set to be the current power if the temperature-jump is higher than a temperature-jump threshold, otherwise, is set to be the previous power limit. The delta power equals to the weighted conversion sum of the temperature jump and the temperature margin, which is the temperature difference between the current temperature and the target temperature. In another novel aspect, the device calculates one or more component power limit for each corresponding component power source of the device based on the total power limit. The device adjusts power settings for each corresponding component power source based on the component power limit.

    Abstract: Techniques pertaining to thermal management for smooth variation in display frame rate are described. A method may involve performing either or both of: (1) determining whether a temperature of at least one portion of an electronic apparatus exceeds a temperature threshold; and (2) determining whether a variation in a frame rate of images displayed on a display device associated with the electronic apparatus exceeds a variation threshold. The method may also involve controlling the frame rate in response to either or both of a first determination that the monitored temperature exceeds the temperature threshold and a second determination that the variation in the frame rate exceeds the variation threshold.
